Why do we need to use assemblies ?

Question

Dear experts I read of a sample project code which contains adds assembly=System.web.extension.desgin and follows by publicKeyToken etc. This is totally new to me. Why do we need to do web application using assembly ? And what is the publicKeyToken about ? From where can we obtain this publicKeyToken ? Also is there any step by step tutorial that covers asp.net web form application based on the above scenario together with stored procedure that I can study and try out things ?
